目的:探讨B超对慢性乙型肝炎(慢乙肝)患者诊断的准确性。方法:对2004年5月—2013年5月收治的160例患者,行肝活检病理检查和B超检查进行对比分析。结果:160例慢乙肝中B超阴性66例,阳性94例;病理学检查肝组织阴性25例,阳性135例,其中诊断为慢性肝炎113例,早期肝硬化22例。慢乙肝中B超肝回声异常与病理肝炎症活动度之间无统计学意义;但慢乙肝中、重度中诊断为肝纤维化和肝硬化的比例分别占60.18%和32.35%。结论:B超检查对慢性肝炎诊断的准确率不高,不能判定肝组织内炎症活动度,但B超诊断为中、重度慢性肝炎患者,应考虑肝纤维化和早期肝硬化的可能。 Objective: To investigate the diagnostic accuracy of B ultrasound in patients with chronic hepatitis B (chronic hepatitis B). Methods: From May 2004 to May 2013, 160 patients underwent liver biopsy and B-mode ultrasonography for comparative analysis. Results: Of the 160 cases, 66 were B-negative in chronic hepatitis B, and 94 were positive. The pathological examination was negative in 25 cases of liver tissue and 135 cases were positive, of which 113 cases were diagnosed as chronic hepatitis and 22 cases were early cirrhosis. There was no significant difference between B-mode ultrasound and chronic hepatitis B in chronic hepatitis B. However, the rates of moderate and severe chronic hepatitis B were 60.18% and 32.35% respectively. Conclusion: The diagnostic accuracy of B-ultrasound for chronic hepatitis is not high, and the activity of inflammation in liver tissue can not be judged. However, B-ultrasound diagnosis of moderate and severe chronic hepatitis should consider the possibility of liver fibrosis and early cirrhosis.
